摘　　要：高等数学是高等教育中一门重要的基础课,导数是高等数学中的一个主要内容。复合函数的求导法则,尤其是多元复合函数的求导法则较为抽象,通过与实例的结合,来研究多元复合函数的情形,再利用变量关系图来解析其求导法则。Higher mathematics is an important basic course in higher education. Derivation is one of the main contents in higher mathematics. The derivative rule of composite function,especially the derivative rule of multiple composite function,is relatively abstract. This paper mainly studies the situation of multiple composite function by combining with examples,and then uses variable relation diagram to analyze its derivative rule.

关 键 词：多元复合函数 求导 变量关系图
